Configuring Remote High-Speed Logging of CGNAT Processes
Overview: Configuring remote high-speed logging for CGNAT
You can configure the BIG-IP® system to log information about carrier grade network address translation (CGNAT) processes and send the log messages to remote high-speed log servers.
When configuring remote high-speed logging (HSL) of CGNAT processes, it is helpful to understand the objects you need to create and why, as described here:
Object | Reason |
---|---|
Pool of remote log servers | Create a pool of remote log servers to which the BIG-IP system can send log messages. |
Destination (unformatted) | Create a log destination of Remote High-Speed Log type that specifies a pool of remote log servers. |
Destination (formatted) | If your remote log servers are the Splunk, IPFIX, or Remote Syslog type, create an additional log destination to format the logs in the required format and forward the logs to a remote high-speed log destination. |
Publisher | Create a log publisher to send logs to a set of specified log destinations. |
Logging Profile (optional) | Create a logging profile to configure logging options for various large scale NAT (LSN) events. The options apply to all HSL destinations. |
LSN pool | Associate an LSN pool with a logging profile and log publisher in order to log messages about the traffic that uses the pool. |
This illustration shows the association of the configuration objects for remote high-speed logging of CGNAT processes.
